TECHNICAL FIELD

The following discussion generally relates to power management inwireless communications systems. More particularly, the followingdiscussion relates to systems, devices, and automated processes thatreduce power drawn by radio frequency (RF) radios based on commercialpower interrupts or failures in 5G data networks or the like by smartbandwidth adaptation and traffic loading increasing the operating timeof the switched backup uninterruptible power supply (UPS).

BACKGROUND

The 5G data standard and telephone networks were developed to providegreatly improved bandwidth and quality of service to mobile telephones,computers, internet-of-things (IoT) devices, and the like. Thehigh-bandwidth 5G networks, however, face additional challenges that arenow being recognized. In part, because of the high-bandwidth, the 5Gbase station is expected to consume roughly three times as much power asthe legacy 4G base stations in use. Further, more 5G base stations areneeded to cover the same area as the legacy 4G base stations. Hence, notonly does each 5G base consume three times the power of the 4G basestation, for coverage of the same area more 5G base stations are in use,and as a result, significant increases in power consumption will result.

Further, along with the increases in power usage, in the case of ACpower outages, the 5G base stations are required to have a batterybackup to ensure service offerings during AC power outages. Thesebattery backup units are expensive, and the cost for the battery backupis in part determined by the amount of power needed and subsequentlyconsumed by the RF radio transmitters and receivers at the 5G basestation; which in this case exceeds the legacy 4G base stations by bothnumber in use and the power need for each 5G base station. In thesecases in which significant amounts of power are needed and consumed bycertain 5G base stations, there is needed several serially or parallellyconnected backup power packs that result in multiple-fold cost increasesin the eventual configured 5G base stations for each cell site.

Therefore it is desired to provide a solution to smartly change theoperating bandwidth (BW) (i.e., the high-bandwidth) at certain cellsites to manage power consumption without causing any cell siteinterruptions in service. It is desired to reduce the power requirementsof all the operating carriers of cell sites in a network, particularlyin case of an AC power outage or interruption for enhanced powermanagement efficiencies of each cell site.

It is, therefore, desirable to create systems, devices, and automatedprocesses that can monitor commercial power interrupts and failures andallow different configurations of base station components to operate inthe desired cell network. It is also desirable to improve connectivityand the operating time for base station equipment operating in backuppower modes using backup batteries at cell sites within 5G or similarnetworks.

Furthermore, other desirable features and characteristics of the presentinvention will become apparent from the subsequent detailed descriptionand the appended claims, taken in conjunction with the accompanyingdrawings and the foregoing technical field and background.

DETAILED DESCRIPTION

The following detailed description is intended to provide severalexamples that will illustrate the broader concepts that are set forthherein, but it is not intended to limit the invention or the applicationand uses of the invention. Furthermore, there is no intention to bebound by any theory presented in the preceding background or thefollowing detailed description.

When connecting a 5G base station to the power grid, this does notalways guarantee that power is available and provided to the 5G basecontinuously all the time without interruption because of a plethora ofenvironmental and operating reasons such as accidents, lightningstrikes, rolling blackouts, etc. Therefore, for a robust and reliable 5Gservice made available from a 5G base station, carriers have to build abackup power system. It is the norm to provide backup power to themacrocells in a 5G network, and often the macro level has sufficientservice. However, the power-consuming small cell structure requiresadded power backup that is not usually available in legacy 4G cell towerpower deployments. Hence, added backup power is essential to enable theproper functioning of the small cell rollout.

In 5G networks, the RF radio units are required to have a battery backupto ensure service offerings during an AC power outage. The batterybackup units are expensive, and the cost for each battery backup iscalculated by the power consumed by the radio unit, the backup duration,and how many operating carriers are at a base station or network.

Currently, there are a number of obstacles or drawbacks that preventoptimization of battery backup capacity when a power interrupt or outageoccurs. It is a desire that the required battery backup capacity can beoptimized as follows:

(1) Shut down Operating carriers: this is not a preferred option, asthis impacts the user experience, lack of emergency calls, such as E911,resulting in users canceling their service and switching to operatorswho have battery backup services; (2) Reduce the operating carrierBandwidth: this is not easily feasible in current operations as changingthe operating carrier BW requires a new cell configuration on the sameradio with lower channel BW, and (3) this will also cause serviceinterruption as changing the operating BW will cause the site to restartfor the new channel BW to be in effect.

The advanced capabilities of 5G small cells mean added powerrequirements. Increased data traffic requires more computational power.Although massive MIMO can help improve spectral efficiency, powerefficiency is generally lower, and a typical three-sector small cell canrequire 200-1,000 watts of power.

There is a need to receive power from a large number of small cells in acost-effective and repeatable way that supports fast and efficientrollouts. The first step involves recognizing that the traditional modelfor powering macro cell sites does not apply to small cells.

The RF radios and antennas use a fixed input power that is based on fullload RF conditions. When commercial power is interrupted, lost, ordramatically reduced, the RF radio is not able to receive notice tomodulate its power consumption accordingly. In other words, the RF isnot informed, nor is the RF radio configured to be advised of acommercial power loss and can change or drop its preconfigured inputpower requirements. The inability to change the input power requirementsof the RF radio results in lower performance in its operation by causinga faster drain on its battery backup systems.

The 5G New Radio (NR) is the global standard for a unified, capable 5Gwireless interface, can deliver a faster broadband experience, and isdesigned to have an initial bandwidth part (BWP) that is used by all theUE during the initial access and dedicated BWP for a UE or group of UEsthat will apply for data allocations. The BWP adaptation is controlledby a gNB node (radio access network (RAN)+distributed unit(DU)/centralized unit (CU) for 5G). There can be multiple smaller BWP(s)that will be predefined by the operator to be used during AC poweroutages (i.e., a RAN slicing architecture that has multiple sets offunctional splits and function placement in one cell). In an exemplaryembodiment, another option is to use a gradual reduction in theoperating BWP. For (e.g., to start with only a 25% percent reduction inBW and then gradually move to lower numbers if the power is notrestored). With this process, the user experience can avoid degradationin the case of short AC power outages. The network slicing can also belinked to the BWP, during an AC power outage or light network loadoperations, the minimization of the power consumption gNB can be done bycontrol of the slice and BWP mutual association. For example, theoperator can choose to merge all the available slices into the smallerBWP. The operator can choose to define the BWP and slice mapping duringan AC power outage when there are multiple BWP defined that are madeavailable during AC power outages.

The virtualization of the radio access network (RAN) of next-generation(5G) wireless systems enables applications and services to be physicallydecoupled from devices and network infrastructure. This enables thedynamic deployment of different services by different network operatorsover the same physical infrastructure. RAN slicing utilizesvirtualization allows the operator to provide dedicated logical networkswith customer-specific functionality without losing the economies ofscale of a shared infrastructure. When implementing these virtualnetworks, mobile devices and other user equipment can experiencechallenges in properly connecting and operating in environments whereeach network provides different “slices” of bandwidth for variousquality of service (QoS).

In reconfiguring to 5G base stations, the 4G two-port transceivers havebeen replaced with four-port radios, enabling the use of multiple-in,multiple-out (MIMO) transmission to improve spectral efficiency. TheMIMO enhances signal strength and helps reduce interference. Eight-portradios take beamforming a step further to provide additional efficiencygains. The nascent 5G technology will take full advantage of beamformingby using 16 or 64 transmit/receive chains (16T/16R, 64T/64R) andradio-integrated antennas operating at 2.3 GHz and higher.

Power amplifier efficiency has improved significantly and is dueprimarily to more sophisticated linearization techniques and higheroutput power capabilities. However, next-generation “massive MIMO”active antenna unit (AAU) radios will require a large number oflower-power amplifiers for each AAU radio. Linearizing each smallamplifier would be costly and marginally effective since the additionalcircuitry would itself consume much of the power it could save, andtherefore is not a feasible solution. In this case, power efficiencycould quite possibly take a turn for the worse.

It is desirable to achieve cost savings using intelligent solutions toreduce the power consumption of 5G base stations when operating in abackup power mode while meeting sufficient regulatory operatingrequirements to prevent a shut-down of the radio transmitter.

It is desirable to limit the number of backup power supplies that areneeded for use when operating the 5G base station in a backup power modefor component cost savings, current usage, and efficiency.

It is desirable to provide systems and methods for operating managementof base stations components that enable the smart management of powerconsumption by implementing adaptable bandwidth control and sliceoffering at cell sites (i.e., nodes) or enabling automated systems toreconfigure components based on examination of the current trafficloading on the antenna to change the mode of operation of the RF radiotransmitter based on evaluating if a degraded RF radio service can beimplemented under the current conditions. If it is possible, the RF EMSor orchestration system will execute a workflow to drop the input powerrequirements on the RF radio. This can reduce the current power drawthat can result in increases in the amount of time the RFradios/antennas can operate in a backup UPS power mode and provideservice.

It is desirable to implement processes where the operator can choose toclose some slice offerings and continue only higher priority slice(s).The Radio AC power outage detection by DU/CU, DU/CU, or NFMF can alsodetect AC power outage via FCAPs and activate the solution. During an ACpower outage, the RAN will notify the control unit (DU: Distributed Unitor CU: Central Unit). The DU/CU will initiate the moving of all usertraffic to the designated lower BWP(s) (e.g., initial BWP) whileshutting down all the other BWP in the current operating carrier. Basedon the configuration, the DU/CU will move all the users and/or slices tothe smaller BWP(s) during an AC power outage or during light networkload to minimize power consumption gNB and will notify the users of thechange in the assigned BWP. The Users will stop monitoring the currentBWP and will immediately start following only the lower BWP.

In a multi-carrier operation, the DU/CU can also move all the traffic toa single carrier based on BWP or slice prioritization configurations.After full power restores or loading on the RAN has increased, gNB canre-activate all the dedicated BWP or slices and move the usersseamlessly to their respective BWP or slice(s). The reduced bandwidthassignment to UE in Multi-User MIMO (MU-MIMO) operation. If the RANScheduler is operating in MU-MIMO operation and decides that all servingusers can be assigned to the same lower PRBs, DU/CU can turn offtransmission on other sub-carriers thereby resulting in power saving.The lower PRBs assignment for MU-MIMO can be prioritized based on BWPand/or slicing predefined priorities.

It is desirable to change required levels on the input power setting ofthe RF radio in response to feedback messages of detected inputcommercial power level changes or interrupts by the RF radio to reducethe operating RF radio power consumption. The RF radio operating powersetting is reduced based on the immediate operational requirements,including determinations of the available RF service on theantenna/radio to provide for a prolonged operating time of airtime ofthe antenna reception and RF radio transmitter.

It is desirable to enable automated systems to reconfigure componentsbased on examination of the current traffic loading on the antenna tochange the mode of operation of the RF radio transmitter based onevaluating if a degraded RF radio service can be implemented under thecurrent conditions. If it is possible, the RF EMS or orchestrationsystem will execute a workflow to drop the input power requirements onthe RF radio. This can reduce the current power draw that can result inincreases in the amount of time the RF radios/antennas can operate in abackup UPS power mode and provide service.

It is desirable to provide systems and methods that when the RF radio ofthe operating cell (i.e., gNB node) incurs a drop or interrupt ofcommercial power at the input to the base station the operationalsystems are altered to compensate for the loss of commercial power to areduce RF radio current draw.

Wireless mobile communication technology uses various standards andprotocols to transmit data between a base transceiver station (BTS) anda wireless mobile device. The deployment of a large number of smallcells presents a need for energy efficiency power management solutionsin fifth-generation (5G) cellular networks. While massive multiple-inputmultiple outputs (MIMO) will reduce the transmission power, it resultsin not only computational cost, but for the computation required, theinput power requirements for transmission can be a significant factorfor power energy efficiency (especially when operating in a backup mode)of 5G small cell networks. In 3GPP radio access networks (RANs) in LTEsystems, the BTS can be a combination of evolved Node Bs (also commonlydenoted as enhanced Node Bs, eNodeBs, or eNB s) and Radio NetworkControllers (RNCs) in a Universal Terrestrial Radio Access Network(UTRAN), which communicates with the wireless mobile device, known asuser equipment (UE). A downlink (DL) transmission can be a communicationfrom the BTS (or eNodeB) to the wireless mobile device (or UE), and anuplink (UL) transmission can be a communication from the wireless mobiledevice to the BTS.

The power consumption of base stations (BSs) is classified into threetypes, which are transmission power, computational power, and power forbase station operation. The transmission power is the power used by thepower amplifiers (PAs) and RF chains, which perform the wireless signalschange, i.e., signal transforming between the baseband signals and thewireless radio signals. The computation power represents the energyconsumed at baseband units (BBU's), which includes digital singleprocessing functions, management, and control functions for BSs and thecommunication functions among the core network and BSs. All theseoperations are executed by software and realized at semiconductor chips.The additional power represents the power consumed for maintaining theoperation of BSs. More specifically, the additional power includes thepower lost at the exchange from the power grid to the main supply, atthe exchange between different direct current to direct current (DC-DC)power supply, and the power consumed for active cooling at BSs.

Power loss and outages are commonplace in networks today as a result ofnatural disasters, rolling brownouts, etc. Base stations include backuppower (e.g., batteries), these forms of backup power may not providesufficient power during lengthy AC power outages, use of commercialwireless communications services may increase due to users' needs and/ordesires.

Operating the BS in a sleeping mode can be a way to reduce energyconsumption in cellular networks; however, this method focuses on theoutput power and does not consider a loss or interrupt of the commercialpower on the input to the B.S. Hence, queueing decision techniques forBS sleeping techniques while can maximize energy-efficient utilizationof the BSs in a green communication network are not applicable whencommercial power is lost to the BS.

The physical or network node either represents an access node (e.g.,Radio Distributed Units) or a non-access node (e.g., servers androuters), while a physical link represents an optical fiber link betweentwo physical nodes. Every physical node is characterized by a set ofavailable resources, namely computation (CPU), memory (RAM), andstorage, which define the load characteristics of a cell. Each physicallink is characterized by a bandwidth capacity and a latency value, whichis the time needed by a flow to traverse that link. Finally, bothphysical nodes and links have associated utilization power requirementsfor each type of available resource.

The power delivery to a BS is rectified and regulated to a nominalmeasured DC voltage 48 (i.e., voltage direct current (VDC)), which isfed to a backup battery or a set of backup batteries for charging. Therectifier unit includes circuitry to keep the batteries fully chargedand ready in case of a commercial power interrupt or failure. At fullcharge, the backup battery is kept at a voltage in the vicinity of 50volts. Also, the vendors/operators may opt for a DC voltage of−24V orother DC voltage setting and not the typical 48V setting. The batterypack parameter in general per customer's requirement is in the order of2-hour work time or other operator backup time settings (e.g., theoperators may choose a 2-hour battery backup, 4-hour or 8-hour . . . asdesired or required for operations) under 100 W (in this case, the poweris calculated per RU power consumption and is a variable quantity . . .) AC system, 48.1V/65Ah battery that can last for about 150 minutes witha full load.

Base stations typically use a 48V input supply that is stepped down byDC/DC converters to 24V or 12V, that can be reduced to meet the DCvoltage level of each module.

In the 3GPP specification, the receive and transmit bandwidth of a UEcan be adjusted to a subset of total cell bandwidth referred to as BWP.The bandwidth can be configured to shrink during a period of lowactivity for power reduction, and also the bandwidth location can bechanged to allow different services. In an exemplary embodiment, thebandwidth adaption can be achieved by configuring the UE with BWP(s)informed to the UE of which of the configured BWPs is currently activeone.

FIG. 1 shows a graphical representation of a 5G or other data network100 that includes multiple cells 121, 122, 123 that provide access to anetwork 105 for any number of UE devices 110. Although FIG. 1 shows onlyone user equipment (UE) device 110 for simplicity, in practice theconcepts described herein may be scaled to support environments 100 thatinclude any number of devices 110 and/or cells 121-123, as well as anysort of network architecture for assigning bandwidth to different slicesand performing other tasks, as desired.

In the example of FIG. 1 , a mobile telephone or other user equipment(UE) device 110 suitably attempts to connect to network 105 via anappropriate access cell 121, 122, 123. In the illustrated example, eachcell 121 includes the components for transmission of a base stationcontroller 131, a base station transceiver 138, a node 140, an RF Radio135, a Radio Network controller 142; the linking components of theantenna interface 132 and the antenna 133; and the power components ofthe commercial power interface 150, the backup power supply 152 of abattery circuitry 154 and UPS or batteries 156.

The commercial power interface 150 may receive power AC power from apublic utility or other sources. The antenna 133 and antenna interface132 control the signal to the UEs 110. The radio network controller 142can control the RF transmit output via the RF radio 135 to conservepower usage to reduce the power draw on the USP 156. By reducing thecommunication bit rate, the RF power can be reduced in decibels (“dB”).Additionally, step reductions can be implemented. The battery circuit154 can be configured as a rectifier type switch that can switch theoutput power from the UPS 156 at multiple levels. The Base Stationcontroller 138 can include power control features to control the powerdrawn by the base station 138. Additionally, the base station controller138 can communicate wirelessly with a power management system 170 thatcan confirm the AC power outage or interrupt on the front end to changethe power input power levels of multiple small cells 121, 122, and 123,and a number of UEs 110 connected to the Node 140 and resources in aslice of a node (gNB).

In an exemplary embodiment, UEs 110 can be configured with a maximum offour BWP for Downlink and Uplink, but at a given point of time, only oneBWP is active for downlink and one for uplink. The BWPs can beconfigured to enable each of the UEs 110 to operate in a narrowbandwidth, and when the user demands more data (bursty traffic), it caninform gNB to enable full bandwidth. When gNB configures a BWP, itincludes parameters: BWP Numerology (u) BWP bandwidth size Frequencylocation (NR-ARFCN), CORESET (Control Resource Set). For Downlink, UE isnot expected to receive PDSCH, PDCCH, CSI-RS, or TRS outside an activebandwidth part. Each DL BWP includes at least one CORESET with UESpecific Search Space (USS) while Primary carrier at least one of theconfigured DL BWPs includes one CORESET with common search space (CSS).For the uplink, UE 110 shall not transmit PUSCH or PUCCH outside anactive bandwidth part. UEs 110 are expected to receive and transmit onlywithin the frequency range configured for the active BWPs with theassociated numerologies. However, there are exceptions; a UE may performRadio Resource Management (RRM) measurement or transmit soundingreference signal (SRS) outside of its active BWP via measurement gap.

In an exemplary embodiment, the radio network controller 131 canimplement logic is implemented with computer-executable instructionsstored in a memory, hard drive, or other non-transitory storage ofdevice for execution by a processor contained within. Also, the radionetwork controller 131 can be configured with a remote radio unit (RRU)160 for downlink and uplink channel processing. The RRU 160 can beconfigured to communicate with a baseband unit (BBU) 139 of a basestation controller 131 via a physical communication link and communicatewith a wireless mobile device via an air interface.

In various alternate embodiments, the base station 138 can be separatedinto two parts, the Baseband Unit (BBU) 139 and the Remote Radio Head(RRH) 141, which provides network operators to maintain or increase thenumber of network access points (RRHs) for the node (gNB), whilecentralizing the baseband processing functions at a master base station175. Using a master C-RAN base station 175, the power management system,170, can be instructed to coordinate operations in the tangent of powerlevels of multiple cells (121, 122, and 123).

FIG. 2 is an exemplary flow diagram of a smart bandwidth adaptation callflow of the smart bandwidth (BW) adapter controller in accordance withvarious embodiments. In FIG. 2 , initially at step 5, the smart BWcontrol is enabled or always configured in on-state monitoring for an ACpower outage or light network load. At step 10, detection by the BWadapter controller is made as to whether a change in state is occurringof an AC power outage or light network load. For example, a feedbackcommunication loop for power management of a base station responsive toa commercial power interrupt or failure of the base station powermanagement system in a wireless data networking environment. Radio ACpower outage detection by distribution unit (DU) or central unit (CU)connected to the 5G network.

The Distributed Unit (DU) or Central Unit (CU) or management function(NFMF) can also detect AC power outage by using the network model ofFault, Configuration, Accounting, Performance, Security (FCAPS) andactivate the appropriate solution. For example, during an AC poweroutage, the RF radio will notify the control unit DU/CU, and the DU/CUunits will initiate moving of all or nearly all of the user traffic tothe designated lower BWP(s) (e.g., initial BWP) while shutting down allor almost all of the other BWP in the current operating carrier.

Next, if there is determined that there is an AC power outage or lightnetwork load at the node, then at step 15, the small BWP(s) will beinitialized. The initial active small BWP(s) are for a UE during theinitial access until the UE is explicitly configured with BWPs during orafter the establishment of the RRC connection. The initial active BWP isthe default BWP unless configured otherwise.

At step 20, move or assigns users to small BWP(s). For example, based onthe network configuration, the DU/CU may move all or nearly all theusers and/or slices to the smaller BWP(s) during the AC power outage orduring the light network load to minimize power consumption. The gNBwill notify the UEs of the change in the assigned BWP. The UEs willcease to monitor the current BWP and will switch to immediatelymonitoring only the lower BWP. In a multi-carrier operation, the DU/CUcan also move all the traffic to a single carrier based on BWP and/orslice prioritization configurations.

The reduction from a wider bandwidth has a direct impact on the peak,and users experience data rates. By operating UEs with smaller BW thanthe configured CBW, reduces power and still can allow support of thewideband operation. At step 25, the adaptive bandwidth module continuesto monitor for an AC power outage or light network load if thecommercial power is resumed then at step 35, the BWP is restored for theentire channel. After full power restores or loading on the RAN hasincreased, gNB can re-activate all the dedicated BWP and/or slices andmove the users seamlessly to their respective BWP and/or slice(s).

At step 40, the normal operation is resumed again, and the powerconsumption levels are raised. Alternately, at step 25, if there isstill determined to be an AC power outage or light network load, then atstep 30, the feedback operation occurs to delay restoring the normaloperation with all the BWPs for the entire channel BW The node is stillplaced in a limited operational state configured with the small BWP(s),and the BW adaptive unit continues to wait for the resumption of thecommercial power or increased loads.

The reduced bandwidth operations and the corresponding assignments tothe UEs can also occur in a Multi-User MIMO (MU-MIMO) operation if a RANScheduler is operating in MU-MIMO operation and decides that all ornearly all of the current serving users can be assigned to the samelower physical resource blocks (PRBs). In this case, the DU/CU units canshut off the current transmission that is occurring on othersub-carriers (i.e., each PRB can consist of up to 12 subcarriers) whichwill also result in power savings of the BS The lower PRBs assignmentsfor MU-MIMO can also be prioritized based on the BWPs active and/or theslicing priorities that have been predefined.

FIG. 3 is an exemplary flow diagram of a smart bandwidth adaptation callflow of the smart bandwidth (BW) adapter controller in accordance withvarious embodiments. In FIG. 3 at step 305, in the smart BW adaptationcall-flow, like in FIG. 2 , the BW adapter controller is initiated, andat step 310 determines whether a change in state is occurring of an ACpower outage or light network load is being operated at the node. If thedetermination is in the affirmative, then at step 315, the initializeslice reassignment process takes place. At step 320, various slices arereassigned to small BWPs from their current slice assignments. Thenetwork slicing is configured that each active slice is tied torespective BWPs which enable during the AC power outage or light networkload the systematic automated transfer of each active slice to a BWP ina scheduled order to reduce the power consumption by the UEs accessingthe gNB by preconfigured slice control and BWP association.

For example, an operator can choose to merge all the active slices inthe network or at a node into smaller BWPs. The operator may choose todefine profiles, settings, etc. of each BWP that make up the BW and alsoalternative slice mappings for assignment during the power interrupt, ACpower outage, light network load, etc. and this can be beneficial whenthere are multiple BWP that can be defined for usage in such conditionswhen the full BW is not needed or when power savings are desired. Theoffering or selections can be assigned all at once, incrementally, andalso can be reassigned to normal operation in a likewise manner. Theoperator also can simply choose to close some slice offerings whendesired and continue to enable only certain higher priority slice(s) foraccess by premium, or both premium and non-premium used. Further, usagecan be selected for an entire preset period or configured for a givenduration to select user sets. In step 325, the BW controller adaptorlike in FIG. 2 , continues to check whether the commercial power has notbeen restored and, if not, then continues via step 330 with theconfigured mapped slices selected for reduced power or load operations.At step 335, once the commercial power is resumed or the load isincreased beyond a certain threshold, all the slices that have beenprior or can be enabled without the prior restrictions will be restored,and normal operations will be restored to all the UE's given access.

FIG. 4 illustrates a functional diagram of BWP parts before and after anAC power outage of an exemplary smart BW adaptation call-flow inaccordance with various exemplary embodiments. In FIG. 4 , in anexemplary embodiment, there is shown an operating carrier (e.g., 20 MHz)with a BWP arrangement 410 before the AC power outage that includes anarrangement of four parts of a set that include (a) an initial BWP, (b)a BWP assigned a number 1, (c) a BWP assigned a number 2, and (d) a BWPassigned a number 3 that make up the entire BWP used by all the UEduring the initial access and the dedicated BWP for a UE or group of UEsthat is used for the data allocation by gNB (i.e., RAN+DU/CU). Also,each BWP 1-3 as well as the initial BWP can contain multiple smallerBWP(s) (not shown). In various alternative embodiments, the multiplesmaller BWP(s) can be predefined by the operator for use in thearrangement during the AC power outage (420). Alternately, the BWP(s)1-3 can be gradually reduced in the operating BWP. For example, a stepapproach in reduction can be used, with 25% step increments in areduction in the BW (i.e., converting particular BWP(s) to an inactivestate) corresponding to a gradually lower number of BWP(s) used. With astep or gradual decrease in the number of BWP(s) active, the BW adaptorattempts to maintain a certain threshold of the quality of service (QoS)of the cell site when short AC power outages take place.

FIG. 5 illustrates a flow diagram of an exemplary slice arrangementbefore and after an AC power outage in accordance with variousembodiments. In FIG. 5 , there shown a slice arrangement 510 with theoperating carrier (e.g., 20 MHz) which is an arrangement of 4 slices ata gNB node before an AC power outage 510, in this case, the slicearrangement is made up of a set of 4 slices of (a) slice assigned anumber zero, (b) a slice assigned a number 1, (c) a slice assigned anumber 2, and (d) a slice assigned a number 3. After the AC power outage520, slice arrangement 530 is reconfigured into two slices of (a) aslice assigned a number zero and (b) the slice assigned a number 1. Inthis case, the slices numbered 1-2 correspond to the reconfigured BWP(s)and specifically to the operating carrier (e.g., 20 MHz) of the BWP partof (a) an initial BP, and the remaining slices are assigned to “allsub-carrier TX with Pwr=0”, in other words in an inactive mode. Asillustrated at 540, the network slicing of an exemplary embodiment ofslice #0 and slice #1 can be tied to the initial BWP. This will enablekeeping enabled slice #0 and slice #1 in the initial BWP. Hence, thereis a two-fold power saving by select slices (i.e., slice #0 and slice#1) and also by the use of only the initial BWP for the selected slices.That is, all the other sub-carriers BWP are shut off—Tx Pwr=0. Theoperating carrier frequency, in this case, remains the same as 20 MHz.Therefore, during an AC power outage or light network load, powerconsumption is minimized first by the slices enabled and then by the BWP(initial BWP) assigned (i.e., the process of merging all the slices in asmaller BWP). The operator can define other BWPs and another slicemapping as desired. It is contemplated that the depicted implementationof merging slices into the initial BWP is one of a variety of ways thatthe moving users to small BWPs and assigning slice offerings tied to theBWP can be performed to achieve power savings.

In an exemplary embodiment, from a network standpoint, a mixeddeployment can be implemented. For example, an exemplary deployment maybe where i) certain cells support slices assigned numbers (0&1) forpremium users with higher power usage and higher transmission rateswhich are assigned to different frequencies than slices 2&3 ofmacro/public cells of lower transmission rates and subsequently lowerpower usage, and ii) certain cells will continue ordinarily when thereis no AC power outage be supporting both sets of slices (0&1) and (2&3).Hence, because of the AC power outage, some cells that would ordinarilybe fully active for premium and non-premium slice access of slices (0&1)and (2&3), respectively, are not enabled. In other words, there wouldnot be any cells that are fully slice enabled, and all the availablecells would have reduced functionalities with not all the slicesenabled, which in turn will result in power consumption reductions aswell as limited slice access with preference to premium users.

In an exemplary embodiment, if a premium user is camped on a cell thatis not a macro cell but does not offer slices 2&3 because of a reducednumber of slices enabled (ordinarily slices 2&3 would be accessible) dueto the AC power outages. In this case, while ordinarily, the user's UEwill frequently not attempt to access slices 0&1, if the slices 2&3 arenot available on another cell because of the AC power outage, the UEability to reselect to another cell will be modified, and the UE willinitiate an attempt to access the available slices 0&1 at the currentcell which the UE is camped.

FIG. 6 illustrates an exemplary flowchart of reassigning users intosmaller BWPs responsive to AC power outages, power interrupts, or lightnetwork loads in accordance with various embodiments. In FIG. 6 , attask 610, an AC power outage is detected or it is determined in responsein a variety of ways, for example via feedback (i.e., messages)communicated and received by the Base Station controller of an impendingAC power interrupt or AC power outage detected in another part of thenetwork or from the monitoring of the input current to the current BaseStation. As a result, at task 620, the adaptive Bandwidth solution isexecuted for changing the current BWP configuration to a new smaller BWPconfiguration. For example, the Base Station may be currently operatingvia a carrier of a select frequency (e.g., 20 MHz) with a complementaryBWP arrangement of four BWP parts of an initial BWP and other BWPs (1 to3) that currently make up the entire BWP in use for the UE (i.e.,essentially all of the UEs in use) connected with the initial access, orthe dedicated BWP for a UE or group of UEs that is currently in use fordata allocation by the gNB (i.e., RAN+DU/CU). Also, in each of theinitial BWP plus BWPs, 1-3 can contain multiple smaller BWP(s). At task630, a multiple set of smaller BWP(s) can be preconfigured for useduring the AC power outage, light network load or power interrupt typeconditions that are occurring. The number of BWP(s) 1-3 is used can alsobe incrementally decreased. With each incremental decrease in the numberof BWPs in use, at task 640, the input power, loading, andcommunications of network power interrupt can also be monitored by theBW adaptor to modulate the number of BWPs in use (i.e., continue todecrease or increase the number of active BWPs) and to keep a certainthreshold of the QoS of the cell site during the changed power or loadconditions.

FIG. 7 illustrates an exemplary flowchart of network slicing responsiveor tied to AC power outages, power interrupts, or light network loadconditions in accordance with various embodiments.

In the flowchart of FIG. 7 , at task 710, an AC power outage isdetected. Also, a lower input power or load consumption (i.e., lightnetwork load) may also be detected or determined in the network, and anetwork slice management algorithm is executed by the BW adaptor tolower slice assignments at the gNB node connected to the Base Station.For example, at task 720, the slice assignments may be assigned to adefault setting for essential services or subsequent assignments forreducing non-essential services. At task 730, the access to the reducednumber of slices that are in use and assigned at the gNB can be balancedfor access between premium and non-premium enterprise users, with thepremium enterprise users given preferential non-essential services solong as QoS can be met. For example, in one scenario, with two sets ofavailable slices, each set may be of slices can have an initialconfiguration of essential services (and only one set having access tonon-essential services) in which premium enterprise users may beassigned access to both sets of slices. The available set of slices withboth essential and non-essential services are then shed in a priorityscheme of assigning access to premium users. The non-premium users areonly given less prioritized access and therefore can only accessessential services that can be shed on a different priority scheme whilemaintaining an appropriate level of QoS. At task 740, the access andpower use of the premium and the non-premium user can be reconfigured tominimize power consumption gNB from the control of the slice and BWPassociation. The operator may select to merge all the available slicesat the gNB node into smaller BWPs. In another example, the operator maychoose to define the BWP and slicing mapping during an AC power outagewhen there are multiple BWP defined to be used during AC power outages.Also, the operator can choose to close some slice offerings and continueonly higher priority slice(s).

At task 750, after full power restores or loading on the RAN hasincreased, gNB can re-activate all the dedicated BWP and/or slices andreassign the users seamlessly to their respective BWP and/or slice(s).The reduced bandwidth assignment at the UE can be done in a Multi-UserMIMO (MU-MIMO) operation. That is, if the RAN Scheduler is operating inMU-MIMO operation and decides that all serving users can be assigned tothe same lower PRBs, DU/CU can turn off transmission on othersub-carriers thereby resulting in power saving. The lower PRBsassignment for MU-MIMO can be prioritized based on BWP and/or slicingpredefined priorities.

FIG. 8 is an exemplary illustration of a UE and network configuration inaccordance with an embodiment. The UE 810 includes a processor 815 forperforming various logic solution functions for registering andreceiving broadcast system information, initiating PDU sessionsperforming cell selections and reselections, ranking neighboring cells,configuring different modes of operation of the UE, etc. . . . . The UE810 may include cell reselection module 825, input/output interfaces805, memory 830 for storing measurement reports, rankings data ofneighboring cells, and a measurement module 835 for calculating byvarious solutions distances and other criteria for neighboring cells,etc. and for accessing cells within the vicinity for the premium andnon-premium users. The network 840 may include a base station 875,processor 845 for registering UE for slice access, cell ID modules 855,broadcast module 848 for broadcasting slice ID, slice offset values forneighboring cells and other system information, authentication module850 for authenticating a UE, network slices 870, etc. and a BWadaptation module 860. The UE 810 communicates with the network andreads broadcasted system information at a cell 910 in which the UE 810is camped in an idle mode. For example, if the UE 810 is camped at acell A, then the UE 810 would receive slice IDs and slice offset valuesfor neighboring cells of cell A via the transceiver 820 and process theinformation via the processor 815 to perform measurements and calculateusing cell reselection equations of the cell reselection module 825(e.g., using a cell reselection logic or process) to select a next cellwhere the cell reselection process is based on a ranking of theneighboring cells.

The BW adaptation module 860 (i.e., BW management unit) can communicatevia element management systems (EMS) 890 (i.e., control unit) to directvarious logic components by an automated workflow of the cell 910 of theparts (shown in FIG. 1 ) of the radio receiver, the UPS, battery circuit(i.e., DC power supply), the cell site (i.e., node) calls/droppedcalls/throughput in operation, the server. The EMS 890 monitors via thedistribution units (DUs) 930 and the central units (CUs) 940 the variousnodes and cells in the network and controls or send instructions to thevarious components of the cell 910 to maintain the quality of service(QoS) of the cell site. The automated workflow maintains the networkavailability and monitors the status of network devices, including thecommercial power supplied to the network. The EMS 890 can also beconnected to multiple eNodeB for power management. When an AC poweroutage in the network occurs, the automated workflow which is monitoringthe network instructs the EMS 890 via various logic components to reducethe output power of the radio receiver and also takes into account otherfactors by communicating with the radio receiver, cell site via a router(or another communication link) connected to the server 920 in reducingthe output power for transmission. This, in turn, reduces the DC powerand the draw on the UPS.

In an exemplary embodiment, the server 920 can be configured as NB-IoTServer is a software for data collection and monitoring andcommunicating via the router for activating the automated workflow viathe EMS 890 and can display the log messages of each base station andthe survival status of all sessions (including information such assignal, power, etc.).

After the detection of an interrupt of the commercial power, powerfailure, power loss, and/or AC power outage of the network, theautomated workflow, which is monitoring the components and the network,detects the change and the power loss. The automated workflow inresponse to the detected power loss implements the configurationmanagement functions via the BW adaptation module 860 of sliceassignments, and available BWPs at cell 910. The EMS 890 communicateswith the radio receiver, the server 920, and other components associatedwith the cell site, to send messages via the cell site router toreceiver collect cell statistics, and to execute appropriate plug andplay functionality of the base station radio receiver. The automatedworkflow executes various functions to the element management systembased on decisions from the BW adaptation module 860 and data from thecell site and base station.
